# Connector and AVR simulator > [!WARNING] > The simulator is intended for light development and testing purposes only and far from being a complete replacement for a real hardware. `qemu-system-avr` tries to use all the CPU cycles (leaving a CPU core stuck at 100%; limit CPU core usage to 10% via `--cpus 0.1`. It can be adjusted on slower machines. ```bash $ podman build -t dcc/connector:sim . $ podman run --init --cpus 0.1 -d -p 2560:2560 dcc/connector:sim ``` All traffic will be collected on the container's `stderr` for debugging purposes.
